That's a very old post indeed 🙂
It would be good to don't depend on Apache Aries Blueprint and make it your own choice which services framework you want to use. Is this something that you would be willing to investigate and develop together with the Activiti development team? Preventing a dependency on the service task implementation is related to this I think, because when you would use an expression or delegate expression this prevents the requirement to define a class name in the BPMN XML file.

Hello Tijs,

thank you for your reply.

That's is in fact an appealing offer :-). I would actually really like to contribute to the Activiti project on that topic if that is desired. In the meantime, I solved the problem in a quite simple way implementing and attaching my own RLResolver implementation. The idea is based on what has been described in the mentioned topic and it works for us. However, I think I would have to go through the solution with other members of the Activiti development team to check if my solution could be improved and made more general.

So what would be the next steps towards a contribution?

I am looking forward to your reply.

Best regards
Timo Rohrberg
